To '1.1.1 whom. vif may concern: t

lle itknown that I, HrzizoN B. LAYMAN, a citizen of the United States, and residing at New Yoi-k. iii the county of New York and State of .\'ew-York', have invented certain new aiidhsefiil- Improvements in Connecting-Leds. ofv which the following is a "-specification. such as will enableA those skilled inthe art to which it appertains to make-and use the same.

This invention relates to connecting rods, and pai:ti iilarly to devices of its class, made from or' composed of sheet metal, and the i `object thereof is to provide an improved device of this class, which is 'composed of two separate longitudinal parts, and the invention consists particularly in the method of securing said parts together, as hereinafter described and claimed. Y

A. The inventionis fully disclosed in the. i following specification, ofwhich the accoman in Y drawin forms a* art in' which P y D g P a the separate parts of my 'improvement are 25' designated .byfzsuitable reference characters `in each of the'views, and in whichz Figure 1 is a side view of the connecting rod, made according to my invention Fig.

^ 2 a section in the line 2-2 of Fig. 1'; Fig. 3

a bottomv plan view of the device,` as shown in Fig. l; and, Fig. 4 across section of the line Muet' Figi 1. y

In the practice of my invention, I provide a connecting rod a, comprising a shank portion a2, a smaller end portion a3, and alarger end vportion a, said end or head portions being provided respectively with the usual .apertures 'or openings as andas, to receive the piston pin and crank shaft of an engine. .The rod a consists of two similar parts b, provided with abutting flanges b2 and b3, and the invention consists in elongating the abutting flanges b'to form an extension b, thereof, whichin the operation of securing the two parts b of the rod a together, are

. folded over the flange members b3, as clearly welding, brazing, or in any other Way, and secured in the larger end portion d* are other sleeve bearingse, provided with end flanges e2.' The larger end .or head 'portion' Aa* is cut, sawed, or otherwise d i'vided'transversely, as shown at f, to form a cap f1, and placed between the -abutting facesof the" rod proper vand the-cap, f2 in the construe! tion shown, areshims'g. The larger end or head portions a, including the cap f2, are

bolts for securing said cap f2 to the rod,

proper, as will be readily understood and `in the usual manner.

It will be understood thatmy invention is not limited to the specific form or constructionof the rod a, or the end or vhead portions a3 and a* thereof, as said invention consists simply in the method of'connecting the separate parts of a rodcomposed of two similar parts, said means consisting in ex- "s also provided with bolt bosses 11 to'v receive tending the flanges of oneof the parts and folding them over the corresponding flanges. of the other part, as clearly shown and de4d scribed', nor is my invention necessarily limited to extending .said overlapping flange 'entirely around said rod, and 'otherchanges in, and modifications of the form of the various parts-of my improved rodmaybe' made within the scope ofthe appended claims, without departing from the spirit of my invention or sacrificing its advantages. v

Having fully' described my invention, what I claim as new and desire'to secure by' Letters Patent, iszl. In a connecting rod, a shank portion Vao composed of a plurality 'of parts one of which embraces another, and a crank' end portion composed of separate parts having bolt bosses formed thereby and therebetween.

2. In a vconnecting rod, a shank portion, composed of `a plurality of parts oneV of which embraces another, and a crank end portion having a cap composed of parts having bolt bosses formed thereby and therebetween.

8. A connecting rod having a crank end portion provided with a cap and composed of a plurality of sheet metal parts one of which embraces another, and means inserted between said parts for securing the cap to' the rod.

4. In a connecting rod, a shank portion' 'tween said and a crank end portion composed of a plurality of parts one of which embraces another, said crank end portion being provided with a cap, and means inserted bed parts for securing the cap to the ro 5. A connecting rod having a crank end portion composed of a plurality of parts one of which embraces another, said parts being p rovided with bolt bosses formed thereby and therebetween. l l

6. A connecting rod having a crank end portion composed of a plurality of parts one of which embraces another, and a cap cut from the crank end portion, the cap and the other part of the crank end portion being provided with bolt bosses formed thereby and therebetween.

7. In a connecting rod, a shank portion and a crank end portion composed of two similar parts provided with abutting flanges one of which is extended and folded over the other, and a cap cut from said crank end'portion, the separate parts of the crank end portion being provided with bolt bosses formed thereby and therebetween.

8. A connecting rod having a cap, composed of a plurality of parts, one of which embraces another.

9. A connecting rod having a crank end portion provided with a cap composed of substantially similar parts one of which embraces another, said cap and the remaining partof the crank end portion being provided with bolt bosses formed thereby and therebetween.

10. A connecting rod having a crank end portion composed of a plurality of parts one of which embraces another, said crank end portion being provided with a cap, and said cap and the remaining part of the crank end portion being provided with bolt bossesformed thereby and therebetween.

In testimony that I claim the foregoing as my invention I havesigned my name in 15;'
